The invention discloses a glass cup forming device and a forming process. The glass cup forming device comprises a forming
machine table, a left frame body, a right frame body, a profiling structure and a conveying belt
assembly, a bottom tray is arranged at the top of the forming
machine table, a lifting groove is formed in the forming
machine table, a first hydraulic rod is installed in the lifting groove, a control
assembly is arranged on one side of the interior of the forming machine table, the left frame body is arranged at the top of the forming machine table, an electric cylinder is installed in the left frame body, and the profiling structure is arranged at the top of the forming machine table. According to the glass cup forming device and the forming process, a vertical frame, a sleeve
pipe, a fire-jet head and a gas conveying
pipe are arranged, the angle of the fire-jet head is adjusted through the vertical frame and the sleeve
pipe, the gas conveying pipe provides a gas source for the fire-jet head, the fire-jet head of the fire-jet device conducts fire-jet heating on the inner side of a spliced mold, the mold is kept at a stable temperature in each pressing process, so that the burst probability of the glass blank is avoided, and the product yield is improved.
